Minecraft Dungeons Seasonal Adventures Season: Funky Portals

So, my idea is to have Funky Portals for a Season of Seasonal Adventures for Minecraft Dungeons. Let me explain the backstory: Archie, as the Arch-Illager, had access to every Illager archive ever. When he turned good from having the Orb of Dominance shattered, he told the Players of a Book he read about Funky Portals (For readers, Funky Portals are Nether Portals with a Book thrown into it in a Java Edition April Fool's Update). The Players create one, and it becomes a Seasonal Adventure. And now for the description: Just like normal Seasonal Adventure, Funky Portals change every 20 days, which also changes their color and content (not Reward content though...). There will be Boxes of Infinite Books next to the Funky Portal. When you go into the Funky Portal, it takes you to a strange place completely randomized. For example, random Mobs will spawn, the terrain is strange, random Blocks will be in the terrain, etc. Feel free to change this idea as much as you want as needed.
